Development Trends of Fiber Optic Communication WDM Technology
This paper presents an overview about WDM technology and recent developments in this field and how the overall capacity of the communication network can be incremented using this technology. Keywords – bandwidth, multiplexing, optical network unit, OCDM, passive. WDM is a technique that enables multiple optical signals to be transmitted over a single fiber optic cable, each at a different wavelength. The application fields of wavelength division multiplexing (WDM) integrated devices are continually expanding.
